Data Log module

Naveen,

Did you every get any information on the DataLog module?

Cheers,

Seán

It's used to pass information to CCStudio for graphing / debu.

See section 2.3.4 of SPRGUI6

http://focus.ti.com/lit/ug/sprugi6/sprugi6.pdf

It's used in all of the Motor Control systems in www.ti.com/controlSUITE

Thanks Chris,

I was under the impression that it was a storage location for Data - i.e. Data Memory that I could use to store a reference sine wave for example and access it whenever I was comparing with my triangular wave. (Especially when you set aside memory on Page 1 in the *.cmd file)

I am also having great difficulty in viewing DLOG_4CH_buff1 with Code Composer - it does not display anything when I set up the graph, or in the watch window, telling me that it can not load from a non-primitive location.

Cheers,

Seán

SeAn,

DLOG_4CH_buff1  is a term used in the assembly file (which we call with the C function in our code)

Have you looked at any of the High Voltage Kit motor control examples in www.ti.com/controlsuite ?

They all use the DLOG function
